gingerbreadgirlJuly 3, 2007

Hello, a few years ago I received in a trade a pretty plant. I think it was suppose to be "creeping jenny" but when I look it up it is not that. Can you help me figure this out. The plant was low,soft-thick mat or mound growing. resembled a vetch but not. Tiny yellow sweet-pea flowers in tiny bunches, and tiny round leaves. Very Pretty. It disappeared from my flower bed. I cannot find a picture of it anywhere. Any help appreciated.
